If you ask Proenza Schouler`s designers Jack McCullough and Lazaro Hernandez what they can't live without, they'll offer the same answer—their dogs.

Instead of going the usual designer-loves-dog route and making cute sweaters for their animals, they made a limited edition run of keychains in the likeness of their pets. Though a pineapple print rash guard would look precious on Lazaro's Prague Ratter, Jojo, a key chain's arguably more useful. Their faces go on sale today on Proenza's site, for $135—click through for a look at Jojo and Buster hanging out, providing inspiration wherever they go!
